ELI KENDALL, OP NEWTON, MASSACHUSETTS. 
IMPROVEMENT IN THE MACHINE FOR BREAKING AND SOFTENING HIDES, SKINS, a'ND LEATHER. 
Specification forming part of Letters Patent No. 229, dated June 10, 1837. 



To all luhom it may concern.: 

Be it known that I, Eli Kendall, of New- 
ton, in the county of Middlesex and State of 
Massachusetts, have invented a new and use- 
ful Improvement in the Machine for Break- 
ing or Softening Hides, Skins, and Leather; 
and I do hereby declare that the following is 
a full and exact description of the said ma- 
chine as invented or improved by me. 

First. I construct a frame about five feet in 
length, four feet six inches in breadth, and 
three feet high. 

Second. I have a cast-iron cylinder or beam 
about fourteen inches in diameter and four 
feet six inches in length, turned straight and 
smooth. 

Third. I have a self-feeding roller on the 
top of the cylinder or beam, which prevents 
the hides, skins, or leather from passing 
through any faster than the cylinder or beam 
revolves. 

Fourth. I have an iron or wooden cylinder 
about four inches in diameter, on which are 
fastened by screws what I term my " spring " 
or "elastic" breakers, more particularly de- 
scribed below. This cylinder, with the break- 
ers, is placed on the top of the other cylinder 
or beam near the self -feeding roller, and per- 
forms the breaking or softening by revolving 
against the hides, skins, or leather as they 
pass through over the cast-iron cj^inder. 

A more definite description of this machine 
will be had by reference to the drawings ac- 
companying this specification. 

A represents the cast-iron cylinder which 
the hides, skins, or leather are carried over, 
passing at the same time under the self-feed- 
ing roller B and the breaker-cylinder C. 

B represents the self-feeding roller. 

C reijresents the breaker-cylinder, on which 
are fastened the spring or elastic breakers, 
which perform the work of breaking or soft- 
ening hides and skins for the lime, and also 
of softening and skiving leather. For more 
convenient description I have marked but 
one of the breakers, which is marked 5 && 6 a 
in Figure 1 on the drawings. They each con- 
sist of a steel plate about five inches in length 
and one-eighth of an inch in thickness. One 
end is cut with a miter, and about one inch 



of the length at this end is bent so as to be 
at right angles with the rest of the plate, be- 
ing the part marked a. The part bhbb is 
the spring of the breaker, and is bent so as 
nearly to fit the surface of the cylinder. The 
part a is that which performs the breaking, 
and has a rounded edge, so as not to cut the 
hides, &c. One end of the part b & 6 5 is 
fastened to the cylinder by the tight screw c, 
and the remainder, with the breaking part a, 
moves in a direction perpendicular to the sur- 
face of the cylinder, the distance from the 
cylinder within which they shall move being- 
regulated by means of the set-screw d. These 
breakers are placed in a direct line around 
the cylinder, being placed in pairs from the 
center, their edges lapping about one-half of 
an inch, so as-to break the joints. As the cyl- 
inder revolves they perform a drawing stroke 
on the hide, skin, or leather, so as not to tear 
or otherwise injure the same. 

D represents the screws for raising andlow- 
ering the breaker-cylinder C a proper space 
from cylinder A, as the thickness of the 
hides, -skins, or leather may require. _ . 

E represents screws forincreasingordimin- 
ishing the power of springs F. 

G represents levers resting across the bear- 
ings of the feeding-roller B. 

H represents weights connected with the 
ends of the levers G for the purpose of bear- 
ing or pressing the feeding-roller B upon the 
hides, &c. 

F represents springs for pressing the break- 
er-cylinder against the hides,' &c., more or 
less, as they may require. 

L represents pulleys or gearing for putting 
the several parts of the machine in motion. 

What I claim as my invention, and desire 
to secure by Letters Patent, is— 

The spring or elastic breakers constructed 
and applied to the machine for breaking or 
softening hides, skins, and leather, as above 
described. 

I do not claim the spiral form of the break- 
ers as my invention.
